CUSHION-SEAT ANID` MATTRESS.

Application filed August 2, 1915.

lImprovement in CushioneSeats and Mattresses, of which the following is a specifi cation.,

My invention relates to cushioneseats or mattresses of the type employing a group of springs inclosed in pockets of fabric or other flexible material and incased in a cover of The pockets for the springs as hitherto provided, while servingto a great degree to reduce the noise in the operation ofthe springs when they are pressed together in compressed condition, do not wholly avoid this undesirable condition, inasmuch as no provision is made for insuring the interposition ofl fabric between the adjacent convolutions of a spring.

My primary object is to avoid the above stated ob'ection, rendering the springs noiseless int eir operation, and to accomplish this purpose by a simple and economical construction. n

Referring to the' accompanying drawing: Figure 1 is a perspective view of a cushionseat constructed in accordance with my invention, .a portion thereof being broken away to disclose interior details; and Fig. 2, a view in sectional elevation of two of the adjacent springs of the seat.

The covering of the cushion-seat is resented at 3 and may -be made of any repdesirable material, as, for'example,leather or tapestry.

The springs which are inclosed within the covering` 3, and form the resilient supporting medium of the seat, are represented at 4, these springs being of the coiled variety as represented, and of a form commonly employed. The springs l are grouped together in parallel relation and in any desired arrangement to lill the covering 3, it being preferred that -they may be provided in parallel rows with adjacent springs directly opposite each other, as shown, though, if desired, they may be arranged in staggered. relation.

According to my invention each sprin 4c is confined in a pocket the walls of'whicl Specification of Letters Patent.

are not common to the pocket of any of the other springs. The pockets, represented at 5,' may be formed of any suitable material' which is flexible and will operate to prevent noise wlien the convolutions of the springs strike each other. The material which I prefer to use is cotton batting which is provided in sheets, though fabric of any suitable character or other material, may be employed.

In practice I prefer to wrap each spring 4. separately in a sheet of the pocket-formsize slightly wider than the length of a spring, the edges of the wound sheet overlapping each other a slight distance, and thereupon tucking the ends of the sheet into the interior of the spring, as

shown. Thus each spring is separately wrapped and cannot contact with adjacent springs. Furthermore, by providing the separate pockets the walls of none of which are common to the pockets for other springs and are free to collapse independently of each other, each pocket, when the spring therein compresses, is free to fold inwardly to become interposed between adjacent convolutions of the inelosed spring, and thus noise from this cause is prevented.

It is further preferred that the springs intermediate their ends, and preferably throughout their length, be secured to the inclosing pockets, in order that by no chance will the adjacent convolutions of a spring directly engage when the spring is compressed. This may be accomplished in any suitable manner, that preferred consisting of dipping the springs, prior to the wrapping thereof in the pocket-forming material, into a bath of glue of any desirable kind which will cause lthe pockets to become firmly attached to the springs throughout the length of the latter and furthermore serve to hold the inturn'ed ends' of the pockets in position.

The springs are held in the covering 3 by any suitable means, those shown being in the forni of clips 6 which engage the Patented J illy 2, 1918.
